The Dark Energy Enigma --"The Entire Universe is Being Pushed by an Unknown Force No One Can Locate"

Adam Riess, who is a researcher at the Space
Telescope Science Institute in Baltimore and also a professor at Johns Hopkins
University was one of the receivers of the 2011 Nobel Prize in physics for the finding
that the universe is expanding at an accelerating rate using imageries of very aloof
supernovae to derive what is now considered the most accurate measurement to
date of cosmic speed. In a recent interview he said “Dark energy is incredibly
strange, but actually it makes sense to me that it went unnoticed.

He continued “I have absolutely no clue what dark
energy is. Dark energy appears strong enough to push the entire universe - yet
its source is unknown, its location is unknown and its physics are highly
speculative”

At the moment, there are numerous theories for the
explanation of dark energy: it could be energy produced by ghostly subatomic
particles that appear out of nothing before annihilating; it may related with
the lately confirmed Higgs Field, which gives definite kinds of matter mass.

Or it can be clarified by string theory by which more
invisible dimensions of space get crushed into sizes much smaller than atoms.

Some theorists even consider that it's an example
of fine-tuning that requires the existence of a multiverse to explain it.

Researchers have established that our universe is
expanding at a rate 20% faster than it was 5 billion years ago. In 1929, Edwin
Hubble first proved that the universe was growing by presenting that galaxies
outside the Milky Way, were moving actually away from each other.

Only about 5% of known the universe is consisted
of planets, stars and gaseous structures, with the remaining 95% covering dark
matter and dark energy. And dark Energy (whatever it is) is responsible for
this expansion.
